Light Sensor KDL43WD752 and EPG event cancelling

[VLD069]

Hi All

Sony Bravia KDL43WD752, two questions:  

1. Is there a light sensor in this model? If there is, how can I turn it off?

2. Through EPG I programmed TV to start on an event few days ahead. The LED indicator is always up in amber. How can I cancel the event?

Thank you!
